COMBINED SHUTTER AND HEATER DEVICE FOR MOTOR VEHICLES.

Application filed April- 21, 1924. Serial No. 707,9.

To all whom it may concern:

Be it known that I, CHARLES H. WILSON, a citizen of the United States, residing at Minneapolis, in the county of Hennepin and State of Minnesota, have invented certain new and useful Improvements in Combined Shutter and Heater Devices for Motor -Vehicles, of which the following is a specification.

My invention relates to combined shutter and heater devices for motor vehicles, and an object is to provide means operating in connection with the radiator for maintaining the water therein and in the entire circulating system in warm condition so that it will not freeze or become unduly chilled when the motor vehicle is standing in the garage in cold Weather. Iaccomplish the objects of my invention by providing for the front of the radiator a shutter frame to which shutters and an electrical heater are attached so that when the shutters are closed and the current is on, cold air Will be prevented from entering and the air surrounding the radiator will be maintained in a warm condition.

The full objects and advantages ofmy invention will appear in connection with the detailed description, and the novel features of my inventive idea will beparticularly pointed out in the claims.

In the accompanying drawings which illustrate the application of my invention in one form, Fig. 1 is a front elevational view of the device applied to the front of a radiator. Fig. 2 is a view in horizontal section on the line 22 of Fig. 1." Fig. 3 is a view in vertical section on the line 3-3 of Fig. 2. Fig. 4 is a fragmentary View of the heating element.

As shown in the drawings, I provide a sglutter frame 10 which is adapted to be soured in front of the radiator 11 by bolts 12. The opening in the frame 10 contains a plurality of pivoted shutters 14 which may be ofany customary or suitable construction and which may be opened and closed in any desired manner. The bottom of the frame 10 'is provided with an outwardly bulged portion 16 with the upper edge of which the lowermost shutter makes I a tight fit when closed. An electrical heating element is placed in the'bulged portion 16. This heating element includes a shell 20 which is positioned in the bulged out portion and is lined with insulating material 22 within which is a resistancecoil 24 wound upon a core 26 of insulating material. The ends of the coil are connected to terminals 28 and 30 by means of which a cable may be connected to an electric light socket or other convenient source of electrical energy.

The operation and advantages of my invention will now be apparent. When the motor vehicle is placed in a garage or even when standing outside the heating element may be readily connected with a source of electrical energy. Current passes through the resistance coil 24 and heats the water in the bottom of theradiator so that circulation is maintained, thereby preventing freezing or undue chilling in any part of the Water circulating system. It will be understood that the shutters 14 are closed at this time and prevent entrance of cold air. Therefore, the shutters and heater cooperate to maintain the water in the circulatin system in a warm condition.

I claim:

1. A device of the class described comprising a shutter frame adapted to be attached to the front of the radiator of a motor vehicle, a plurality of shutters mounted in said frame a portion of said frame being bulged outwardly, an electrical resistance element mounted in said bulgedout portion and means whereby said element may be connected to a source of electrical energy.

2. A device of the class described comprising a shutter frame adapted to be attached to the front of the radiator of a motor vehicle, mounted in said frame, the lowerportion of said frame being bulged outwardly and the lowermost one of said shutters when closed making a tight fit with the upper CHARLES nwmsoN.
